Tips: How to Install Capacitive Hydraulic Oil Level Sensor?

Capacitive Hydraulic level sensor offers exceptional installation versatility across industrial and vehicle applications: It can directly replace the factory-installed oil level sensor in commercial vehicles, construction machinery, and similar equipment, seamlessly fitting into the original tank mounting positions without additional modifications. Alternatively, it supports custom drilling installations on tank surfaces—ideal for retrofitted equipment or auxiliary tanks requiring new liquid level monitoring, and compatible with most metal or rigid plastic tank constructions.

To ensure a secure, leak-proof installation with long-term stability, follow this standardized process: First, drill a precise hole at the designated mounting area on the tank, apply a uniform layer of sealant, insert the rubber gasket, and fasten the matching flange firmly; this step is critical to prevent future fluid leakage. Next, fit the sensor with an O-ring (inspect the ring for damage before installation) and screw the sensor into the flange until the threads engage tightly. Then, connect the sensor wires according to the wiring specification to ensure correct signal transmission. Finally, attach the anti-tamper lock for enhanced security, and use cable ties to neatly secure the wires—this prevents cable abrasion from vibration, completing a reliable installation.
